A Data Aggregation System using Mobile Agents on Integrated Sensor Networks

Abstract—Due to the recent development of sensor networks, integrated sensor networks, in which some sensor networks are managed systematically, have attracted considerable at-tention. To implement various applications, such as weather forecasting and environmental observation, with integrated sensor networks, users (clients) usually aggregate and collect the sensor data obtained from all the sensor networks. After this, the clients execute some operations, such as averaging and analysis, on the aggregated sensor data. However, such processes cause heavy network traffic in aggregating data from all the sensor networks. Hence, in this paper, we propose a data aggregation system using mobile agents. Mobile agents are programs that migrate among sensor networks. Since the mobile agents migrate while executing operations on the sensor data, the clients do not need to aggregate the sensor data by collecting it from all the sensor networks, and the network traffic can be reduced.
